With a two-level turbine with reverse rotating directions adopted, thermalconversionefficiency can be greatly improved.
采用两级旋转方向相反的涡轮可使热转换效率大大提高。

Photothermal techniques can provide the information that pure optical spectroscopy is not able to give, such as optical-to-thermal energy conversionefficiency.
光热技术可以提供纯光学光谱学所无法提供的、类似光-热能量转换效率之类的信息。

Specially, the thermal lens effect is intensified due to the long tail attached to pulse, which leads to decreasing of conversionefficiency if pulse repetition rate is enhanced.
